  • A logical operator that consists of a logical and followed by a logical NOT and returns a false value only if both operands are true.

    逻辑其后逻辑组成的逻辑运算符如果两个运算都是真,则返回便假。

  • The logical operators have lower precedence than the individual comparison operators, which makes sense because the comparison has to be evaluated before the logical operator can be evaluated.

    逻辑运算优先级低于单独比较运算符,一点意义重大,因为必须计算比较运算符,然后才能计算逻辑运算符。

  • It's best to read such execution plans from the left-lowest operator in the tree, since the logical flow in the plan is from bottom to top and left to right.

    因为执行计划中的逻辑自下而上、,所以此类执行计划时,最好是从左下方的操作符开始。
